To meet the normal operating temperature range requirements, it is necessary to ensure effective thermal dissipation,
e.g., by adding passive or active heat sinks, heat pipes, vapor chambers. Within this range, the module's indicators comply
with 3GPP specification requirements.

To meet the extended operating temperature range requirements, it is necessary to ensure effective thermal dissipation,
e.g., by adding passive or active heat sinks, heat pipes, vapor chambers. Within the extended temperature range, the
module remains the ability to establish and maintain functions such as voice, SMS, and data transmission, without any
unrecoverable malfunction. Radio spectrum and radio network are not influenced, while one or more specifications, such as
P , may exceed the specified tolerances of 3GPP. When the temperature returns to the operating temperature range, the
out
module meets 3GPP specifications again.
